First of all, great books guys, I bought both EPI and EPI-Java PRINTED books, helps me keeping my Interview Preparedness on the edge
Now to the E-Books issues: Adobe Digital Editions (ADE) App allows you to read EPI books bought on Google Play Books on Windows (native app), Mac (native app) and Linux (virtualization of Windows plus Windows ADE app)
I actually verified all three because I could not read EPI-Java I bought on Google Play Books in ADE for 3 days while I was getting E_GOOGLE_DEVICE_LIMIT_REACHED in ADE and calls to Google went nowhere for a day or two, then I started getting E_LIC_LICENSE_SIGN_ERROR and instead of just giving up (like a regular user would) and ask for a refund, I bought two other Google Play Books for 99 cents to troubleshoot (that’s what we engineers do)
So I kept getting same errors across all 3 Google Play Books on both Windows and Mac ADE apps, then I decided to DIG DEEPER and I bought another ADE-encrypted e-book from Kobo and I also found that you can get free ADE-encrypted e-books from Overdrive by “Virtual Check Out from Local Library” using Local Library ID, so I got several of those.
By that time I also found out that ADE App written by Adobe requires Adobe Content Server (ACS) deployed on Publisher side (Google Play) and that ACS written in JAVA and that when you click “Download PDF” in Google Play Books for EPI you actually download .acsm file that is XML-based, so I actually compared them all against each other: Google, Kobo and Overdrive and found quite a few differences (and they supposed to be the same?)
I also found on Adobe Forums that ADE errors E_LIC_LICENSE_SIGN_ERROR is mis-configuration of ACS and needs to be fixed there (on Google’s servers, not Adobe’s servers)
After sending all of that through “Contact Us” using “Call Us” making sure it’s properly logged, E_LIC_LICENSE_SIGN_ERROR disappeared in a day or two.
Now to the remaining problem, FUZZINESS of the EPI-JAVA in Chrome Web Browser, ADE App, iPhone Google Books App, Android Google Books App: It MIGHT look OK, as in “Well, It’s SCANNED BOOK what do you expect?” until you realize IT IS NOT SCANNED BOOK ???
VERY EASY TO REPRODUCE: ZOOM IN TO MAX for both EPI SAMPLE PDF from this website (NOT Google Play Books!!! ITS THE SAME SCANNED PDF) AND Google Play Books SAMPLE EPI Books.
EPI SAMPLE PDF from this website looks CRYSTAL CLEAR when ZOOM IN TO MAX AND reading normal.
EPI SAMPLE from Google Play Books LOOKS HORRIBLE EYE-DESTROYING FUZZY when ZOOM IN TO MAX AND VERY DISTRACTING when readling normally.
I’m going on the trip next week and I opened case with Google Play Books support that if they don’t resolve it until then and I have to take printed book with me, then there is no reason for me to keep EPI-JAVA in my Google Play Books account (I will happily buy it again when this issue is solved)
Here is Android phone with Google Play Books app ZOOM IN TO MAX on top of EPI PRINTED book: http://imgur.com/a/Ssu07 and http:// imgur.com/a/8GXeS (click on images to get larger view)
Compare those HORRIBLE FUZZY images with these CRYSTAL CLEAR images (EVEN WITH HIGHER ZOOM!!!) of EPI-JAVA SAMPLE PDF downloaded from this website on the same Android phone: https://imgur.com/a/1TDRz and http:// imgur.com/a/d8SjB (click on images to get larger view)
